Phones disappear in every possible way. Left in a taxi, dropped off a dock, lifted from a bag in a crowd, or handed back to a carrier at the end of a contract while a replacement ships. If you track a GLP-1 in an app, a second and smaller worry tends to arrive about an hour after the first one: what happens to the log?
Because this app's privacy design is unusual, the answer is not the standard just-sign-in-again reply that most software gives. So here is the whole picture, honestly: what is actually on the phone, what survives and how, the two checks worth making today, and what to do if the log is already gone.
The honest answer first
If a log lives only on one phone, and that phone has no backup, the log goes when the phone goes. There is no gentler way to say it, and pretending otherwise would not help you plan.
That fragility is the cost side of a design we believe in. The app has no account and keeps no copy of your data on any server, which means nobody at our end can look your log up, reconstruct it, or send it back to you. There is nothing to send. The full case for that architecture, and why we think the privacy is worth the trade, is laid out in Why Your GLP-1 Data Should Stay on Your Phone.
The flip side of the honest answer is that the survival of your log is decided by one thing entirely under your control: whether the phone itself is backed up. An iPhone that is backed up carries the log with it through every kind of loss. An iPhone that is not, does not. Most of the rest of this article is about that one setting, and about how to check it before you need to have checked it.
Where your log actually lives
The app keeps everything you log in its own store on the device. Doses, weights, meals, side effects, notes and targets all sit in that store, and the store sits in the ordinary place iOS keeps app data. There is no login, no sync and no second copy anywhere else.
Progress photos are stored as files kept beside that store. They are app data in every sense that matters here, and every rule in this article that covers the store covers them too.
One category of information has a second home. If you have connected Apple Health, the readings the app imports, which are weight, steps, active energy and water, live in Apple Health as well as in your log. On a restored phone they will still be in Health, whatever happened to the app's own copy. Our article on GLP-1 Tracking and Apple Health: Better Together explains what that connection adds and how to control it.
What a backup captures, and what to check
The single most important sentence in this article: the app does not opt out of backups. Your log is part of what an iPhone backup captures, whether that backup is iCloud Backup or an encrypted backup made on a computer. Restoring such a backup onto a new iPhone brings the log back with it, and so does transferring directly from the old phone during setup.
Notice what that sentence does not say. It does not say a backup exists, or that it ran last night, or that it covers this app. Those are settings and facts on your phone, and they are worth checking rather than assuming. iOS lets you exclude individual apps from iCloud Backup, and any app can land on that list, this one included, sometimes without you remembering how it got there.
The walk to the list is this: Settings, then your name, then iCloud, then Storage or Manage Account Storage, then Backups, then the device you are using. Apps included in the backup appear with their toggles. One caution that matters: turning an app off in that list does not merely skip it in future backups. It also removes what that app had already stored in iCloud. So if you find the app switched off, treat that as the finding it is, switch it back on if you want the log covered, and verify a day later that a backup ran.
Two neighboring facts are worth knowing while you are thinking in this direction. Deleting the app removes its data from the device. Offloading, which iOS offers when storage runs short, frees the space the app itself takes while keeping its data on the device. And Premium is tied to the Apple ID that bought it, not to the handset, so it comes back on new hardware through Restore purchases rather than through any transfer of logged data.

Get the app
Setting up a replacement phone
When a replacement iPhone arrives, setup offers you a fork: transfer directly from the old phone, or restore from a backup. Both paths carry the app's store and its photos across as ordinary app data, and a restore puts the Apple Health readings back where they were.
Direct transfer is the option you want when the old phone still exists and still boots: it moves the current state across wholesale, and the app comes up on the new device looking exactly as it left the old one. Restore from backup is the option that matters when the old phone is gone, drowned or unresponsive. In that case the most recent backup is the whole story, which is a clean argument for having checked, in the previous section, that backups were running and that the app was on the list.
After either path, open the App Store and make sure the app is installed, and if you subscribe to Premium, use Restore purchases to bring it back under your Apple ID. There is no account to recreate and no password to remember, because there never was one; the data arrived with the phone's data, and the subscription arrives with your Apple ID.
Two things worth doing today
Both checks take minutes, and neither needs a lost phone as a reason to do them:
- Check that the app is included in the device backup. The five-tap walk through Settings described above, done once on a quiet evening, is far better than doing it in the first hour after a loss. While you are there, confirm a backup ran recently.
- Keep an export somewhere you control. Premium export writes your log to a file that you can save anywhere you choose. Understand what it is before relying on it: a readable copy for you and for the people you hand it to, and not a restore path, because the app cannot import an export back in. What is inside the file, and what it is for, is covered in Exporting Your GLP-1 Data: What It Is For.
Together those two habits mean the log survives in independent ways: as part of the phone's backup, which covers everything without your thinking about it, and as a file you can point to and read, which covers the scenario where the backup itself is out of reach.
If the log really is gone
If no backup existed and no export was kept, the log is gone. Saying that plainly is more useful than softening it, because what follows the sentence is genuinely recoverable, and knowing where to start keeps the loss from compounding.
Dose dates are the part worth reconstructing first. They anchor everything a prescriber asks about, from where you are in a titration schedule to how the medication has been tolerated, and they are the hardest thing to rebuild from memory precisely because memory smooths over gaps. Two places usually hold them: pharmacy refill records, which your pharmacy can show you or print, and the pens themselves, whose cartons and remaining doses carry evidence of when each one was in use.
From today forward, the app starts fresh, the way any new log starts. A rebuilt dose list from refill dates, plus normal logging going forward, closes most of the gap that matters clinically. Weight readings, if Apple Health was connected, may still be sitting in Health on the restored phone, since they lived there independently.
And once the new log is running, the two checks from the previous section are no longer abstract. A phone that has already eaten one log deserves a backup that is verified to exist.
Frequently asked questions
If I lose my phone, is my GLP-1 log gone forever?
It depends entirely on whether the phone was backed up. The app keeps everything on the device, with no account and no copy on any server, so nobody at the app's end can look your log up or send it back. An iCloud Backup or an encrypted computer backup that included the app will bring the log onto a replacement iPhone, and so will transferring directly from the old phone during setup. A phone with no backup takes the log with it when it goes.
How do I check that GLP 1 Tracker App is included in my iPhone backup?
Open Settings, tap your name, then iCloud, then Storage or Manage Account Storage, then Backups, then the device you are using. The list shows the apps included in iCloud Backup. Find the app in that list and make sure it is turned on. Be careful when toggling: turning an app off in that list also removes what it had already stored in iCloud, not just future data.
Will my Premium subscription work on a new phone?
Yes. Premium is tied to the Apple ID that bought it, not to the handset. After setting up the replacement phone, sign in with the same Apple ID, reinstall the app, and use Restore purchases. The subscription comes back through Apple independently of your logged data, so it survives even in the unhappy case where the log itself did not.
Can I restore my log from an export file?
No. The app cannot import an export back in. An export is a readable copy of your log, in a form you and the people you choose can open and read, and that is all it is. Keeping one somewhere you control is still worth doing, as a record you can see with your own eyes, but it is not a restore path and will not put data back into a new install.
What happens if I delete or offload the app?
Deleting the app removes its data from the device, so the log goes with it. Offloading is different: it frees the space the app itself takes while keeping the app's data on the device, which is why iOS offers it. If you offload by accident, reinstalling brings the app back with its data still in place. Either way, a backup made before the deletion still contains whatever was captured at the time.
